(Current limit)
Value:
0.0 - I
VLT,MAX
Max. allowable output current. The
factory-set value corresponds to a 160%
load of the rated motor size.
Not applicable to all types.
Settings between 105% and 160% may
only be applied on intermittent operation.
If the set value is too low the motor will not
start.

Warning
frequency low (f
LOW
)
(LOW freq warn)
Value:
0.0 - f
RANGE
✭
0.0
This value sets the lower warning frequen-
cy f
LOW
of the normal frequency converter
operation range, see page 71.
If the output frequency is below f
LOW
the
display shows FREQ. VAR. LOW.
The signal outputs can be programmed
to give a warning signal (parameters
407-410).
211
Warning
frequency high (f
HIGH
)
(HI freq warn)
Value:
0.0 - f
RANGE
+ 10%
✭
132 H
Z
This value sets the higher warning frequen-
cy f
HIGH
of the normal frequency converter
operation range, see page 71. If the output
frequency is higher than f
HIGH
the display
shows FREQ. VAR. HIGH. The signal out-
puts can be programmed to give a warning
signal (see parameters 407-410).
This value sets the lower warning current
I
LOW
of the normal frequency converter op-
eration range, see page 71.
If the output current is below I
LOW
the
display shows CURR VAR. LOW.
You can program the signal outputs to give
an alarm signal (see parameters 407-410).

I
VLT,MAX
This value sets the higher warning current
I
HIGH
of the normal frequency converter op-
eration range, see page 71. If the output
current is higher than I
HIGH
the display
shows CURR VAR. HIGH. The signal out-
puts can be programmed to give a warning
signal (see parameters 407-410).

Ramp type
(Ramp type)
Value:
✭
Linear (linear)
[0]
Sine shape (s curve 1)
[1]
Sine
2
shape (s curve 2)
[2]
Sine
3
shape (s curve 3)
[3]
Select the shape of the ramp up and the
ramp down. The sine shapes give a softer
start and stop of the acceleration and
deceleration.
The sinusoidal ramps cannot be set with
steps as small as the linear ramp, even
though the display indication appears to be
continuous.
